不同梨品种果实营养成分含量的分析结果表明：果糖、葡萄糖和蔗糖是梨果实中的主要糖类，品种间三种糖的含量有较大差异，所测品种果实中三种糖的含量范围分别为：3.40%～9.24%、0.21%～2.72%、0.10%～1.69%；可滴定酸的含量以八月红最高(0.286%)，爱宕最低(0.078%)；维生素C的含量以博斯克最高(9.50 mg/100g)，绿宝石最低(1.89mg/100g)；不同品种间可溶性蛋白和氨基酸的含量差异较大，其含量范围分别为127～428mg/100g和77.4～24.8 mg/100g；不同品种间同一矿质元素的含量存在较大差异。

AMF-inoculation significantly increased the contents of total soluble solid, soluable sugar and titratable acid in fruit of cherry tomato.

结果表明：接种菌根真菌能够显著提高植株根系菌根的侵染率和果实干重；接种对品质的改善表现在果实中的可溶性固形物、可溶性糖和可滴定酸的含量明显提高，糖酸比适中，果实风味品质好。

At the optimal condition, the amount of decrement and time form liner relationship and acidic trehalase activity is 338.6mg/.

在此条件下，海藻糖的消耗量与时间成线性关系，并得出该菌的酸性海藻糖酶活性为338.6mg/。

To utilize trehalose,it must be hydrolyzed by trehalase for glycolysis.

海藻糖必须被海藻糖分解酶分解成葡萄糖才能用于糖酵解，以提供昆虫能量的需求。

The developer, trehalase amount, trehalose amount, reaction time and temperature, solvent were discussed. Validoxylamine test showed that the method of trehalase-inhibit in vitro is reliable for screening.

离体测试模型主要涉及溶剂的选择、显色剂选择、反应的温度和时间、海藻糖酶和海藻糖的用量等内容，所建立的离体测试模型用井岗霉素验证了该方法的可靠性。

Validamycins have been one of the most popular and economical biopesticides in China, by microbial transformation of which validoxylamine A and valienamine can be produced. Validoxylamine A has strong inhibition on trehalase and it is a new promising insecticide. Valienamine demonstrates strong glucosidase inhibitory activity, which can also be used as intermediate in the synthesis of medicines for diabetes.

井冈霉素目前已成为我国最经济最受欢迎的生物农药之一，用微生物转化法分解井冈霉素可以得到井冈霉亚基胺A和井冈胺，前者对海藻糖酶有强烈的抑制作用，有望开发成为新型生物杀虫剂，而后者是一种糖苷酶抑制剂，也可作为合成降糖药的原料。

This reflected that EMP and HMP pathways and the tricarboxylic acid cycle were very important to the bioreduction.

表明糖酵解途径、磷酸戊糖途径和三羧酸循环的顺利进行对于面包酵母在有机介质中催化4-氯乙酰乙酸乙酯还原反应都是十分重要的。

While at Phase IV, with specific growth rate increasing, the carbon flux of PP decreased gradually, and the carbon flux of Tricarboxylic Acid Cycle, which providing enough precursors and energy to synthesize human-like collagen, decreased slightly with specific productivity of human-like collagen increasing.

在第Ⅲ阶段，随着比生长速率的增大，进入磷酸戊糖途径的碳流量先增大后减小，当比生长速率为0.15h~(-1)时达最大值，其次是0.20h~(-1)的，以合成足够的前体和NADPH满足细胞生长所需；在诱导后，随着比生长速率的增大，进入磷酸戊糖途径的碳流量逐渐减小，而进入三羧酸循环的碳流量随着类人胶原蛋白比产率的增大而稍有减小，以提供足够的前体和能量合成目标蛋白。

Result At 5 and 25 mgkg^(-1), the total respiratory rate had a similar trend with tricarboxylic acid cycle and pentose phosphate pathway, T1, and T2 were higher than the control on the 1st day and then declined three days late but they had a recover on the last day. Embden-Meyer-hot-Parnas pathway had a declined trend forever. The respiratory rate of the total and three pathways were decreased under 125 mgkg^(-1). The enzyme activity of pyrophosphate-dependent phosphofructokinase, glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase were similar to relative respiratory pathway.
